Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
To Dress Fish
Ingredients
Directions
Prepare the fish
Boil flat fish carefully until cooked through without breaking, then drain and cut off the fins.
Flour the fish before broiling, except for herrings, which should be scored with a knife.
Dry the fish with a cloth and flour them before frying in hot dripping or hog's lard.
Fry the fish until golden and drain on a dish or hair sieve.
Make the sauce
Wash parsley and dip it in cold water.
Fry the parsley in boiling fat until crisp and green.
Combine chopped shallots, anchovies, bay leaf, scraped horseradish, lemon peel, and red port in a pot.
Season the mixture with Cayenne pepper, coarse sea salt, and lemon juice.
Boil the mixture until thick.
Strain the sauce over the fish and stew gently.
Serve
Serve the fish in a deep dish with the sauce and fried bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flat fish
- Forms the main body of the dish, cooked through by boiling and then frying.
- Flour
- Coats the fish so it browns during frying and helps keep the skin intact.
- Red port
- Adds sweetness and depth to the sauce as it reduces.
- Anchovies
- Contribute savoury, salty depth to the sauce as they cook down.
- Lemon juice
- Adds acidity that brightens the rich sauce.
- Scraped horseradish
- Adds a sharp, pungent aroma and bite to the sauce.
The step that matters
Boiling the sauce until thick. Reducing the port and aromatics concentrates flavour and thickens the sauce. If it is under-reduced it will be thin and watery, and if it boils too hard the port can turn harsh and bitter.
Swap the horseradish
How well each one fits the dish's main ingredients (fish, parsley, flour, pepper, lemon, shallot, bread):

Fit is the average pairing score against fish, parsley, flour, pepper, lemon, shallot, bread. Candidates are from the same food group and used in at least 100 recipes.
